Here's a patch that seems to get sysconfig minimally working under NT for me. Has anyone else done better?
I noticed that distutils installs itself under 'lib\site-packages' which does not seem to be a convention under NT, at least the directory does not exist by default, and is not in the Python path by default. It seems that Windows packages normally go in the top level Python directory--at least that's where the win32 packages install themselves, and it *is* in the Python path by default...
Anyway here's the simple-minded patch.

It directory is added by site.py, which is imported when you start python (unless you use "python -S"). Quoting from it: | This will append site-specific paths to to the module search path. On | Unix, it starts with sys.prefix and sys.exec_prefix (if different) and | appends lib/python<version>/site-packages as well as lib/site-python. | On other platforms (mainly Mac and Windows), it uses just sys.prefix | (and sys.exec_prefix, if different, but this is unlikely). The | resulting directories, if they exist, are appended to sys.path, and | also inspected for path configuration files.
Regarding the fact that the directory doesn't exist, I just checked the unix install and it doesn't seem to create that directory either. Rather, I just did:
make -n install | grep site
and didn't find anything. Also, I see my "site-packages" directory has the wrong unix group and creation time, so it must have been created manually.
Anyway, lib's "site-packages" is the official place for installing Python packages.
from your patch:
g['LIBDEST']=os.path.join(sys.exec_prefix, "Lib") g['BINLIBDEST']=os.path.join(sys.exec_prefix, "Lib")
Is that really "Lib" or just "lib"? Granted, it is NT which means I know nearly diddly about it.

Exactly. On Windows, the site directory is just sys.exec_prefix, rather than sys.exex_prefix/lib/python<version>/site-packages.
So now we need additional fixes to distutils to handle this platform difference.

On Unix ;-)

I guess it should be 'lib'. I don't know. I just used 'Lib' cause that's what the some other Python path directories (set in the registry) call it...
OK, here's two patches, one to handle the site-package platform differences, another repeat of my last one, only this time with 'lib', not 'Lib'

With these patches distutils installs itself correctly on NT for me.
